SHADE-ROLLER.

Application led May 21, 1915.

To all whom t may concern.'

lie it known that l, Ci-innnns M. FERGUSON, a citizen of the United States, residing at Victorville, in the county of San Bernardino and State of California, have invented certain new and useful improvements in Shade- FLollers, of which the following is a specifr cation.

This invention relates to shade rollers, the primary object of which is to provide a roller which may be expeditiously mounted in the window casing and removed therefrom at the option of the operator.

Another object is to provide a friction brake means by which the window shade may be held in a predetermined adjusted position,

Other objects as well as the nature, characteristic features and scope of my invention will be more readily understood from the following description taken in connection with the accompanying drawings and pointed 'out in the claim forming a part of this specification.

Referring to the drawings:

Figure 1 is a front elevational view of a shade roller constructed in accordance with my invention, a portion thereof being shown in section and a portion being broken away to disclose details,

Fig. 2 is a cross sectional view taken on the line 2--2 of Fig. 1 and looking in the direction of the arrows,

Fig. 3 is a side eleva-tional view of one of the casing brackets used in the present invention, and

Fig. 11 is a similar view of the other casing bracket.

ln the drawings, a window casing 1 is provided which may be of the usual or any desired configuration, and which is shown in Fig. 1 in order to illustrate the application of my invention.

Mounted upon the front face and upon opposite sides of the casing 1 is a pair of brackets 2 and 3, the former comprising a base having an ear t extending outwardly from the front face of the base and at right angles to the latter, and being provided on its inner face with a stud or pintle 5, as illustrated to advantage in Fig. 1. The base of the bracket 2 is engaged with the casing 1 by screws or any other suitable detachable fastening means. rlhe bracket 3 also comprises a base plate which is 'detachably engaged with the casing 1, by screws or any Speciicaton of Letters Patent.

other suitable fastening means, and has extended outwardly froin its front face an ear 6 which has projecting laterally from its inner face a socket 7.

The ro-ller is indicated in the drawings at 8 and is of the usual configuration, being provided in one end with an axial recess 9 in which an expanding coil-spring 10 is mounted. A pintle 11 entends from the opposite end of the roller 8 and is revolubly mounted in the socket 7 of the ear on the bracket 3, as shown to advantage in Fig. 1.

A. drum 12, which in the present instance is of a cylindrical configuration, and preferably tubular, is mounted upon the stud 5 of the bracket 2, and has one of its ends enlarged to provide an annular flange 13 with which one end of an operating cable 111 is ixedly engaged. The opposite end of the drum 12 is provided with an enlarged cap 15, which is snugly engaged with the recessed end of the roller S and is held in engagement with the latter by screws 16, as shown to advantage in Fig. 2;

A. Heating tube 17 is arranged on the interior of the drum 12, being preferably of a cylindrical configuration, having one end closed for engagement with the free terminal of the stud 5, the opposite end being open and adapted for the reception of one end of the coil-'spring 10. rFhe tube 1'? serves in the capacity of a brake member, since the closed end thereof will normally frictionally engage the free end of the stud 5 by the pressure exerted thereon, in view of the coil-spring 10, since a convolution on one end of the latter is snugly engaged with the roller 8 at the inner end of the recess 9, while the convolution on the opposite end is engaged with the closed end of said tube, normally forcing the same outwardly toward the bracket 2.

A shade 18 is associated with the roller 8, in the usual manner, and is adapted to rotate the latter when the shade is pulled downwardly, so as to permit lowering the latter to the desired point of adjustment.

ln operation therefore assuming that the shade is in a rolled-up position on the shade roller, and it is desired to lower the same, the shade is pulled downwardly in the usual manner so as to cause the same to be unwound from the shade roller 1S, and is retainable at any desired point while being flowered, automatically by the frictional brake means caused by contact between the closed end of the tube 17 and the free end of the stud 5. When it is desired to raise the shade, pressure is exerted upon the cable 14, thereby rotating the drum and causing the roller 8 to rotate in a direction opposite to that taken when the shade is being lowered7 thereby causing the shade to be rolled in the usual manner upon the roller 8.

it will be understood that the above description and accompanying drawings comprehend only the preferred embodiment of my invention, and that various minor changes in details of construction7 proportion and arrangement of parts may be made within the scope of the appended claim without sacrificing any of the advantages of my invention. Y

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

A device as specified including a roller7 a drum associated with one end of the roller, a bracket for engagement with the window casing and provided with a stud to engage said drum, a tube inovably mounted upon the interior of said drum for coaction with said stud, an elastic element mounted in said drum and engaged in said tube to normally force said tube into engagement with said stud for holding the roller in a stationary position, the latter being movable when pressure is exerted upon the shade, a bracket for engagement with the opposite end of the roller7 and an operating cable associated with said drum to rotate said roller for winding the shade 0n the latter.

In testimony whereof I aflix my signature in presence of two witnesses. Y
